ALVA L. KI'ISELMAN, OF RIDGEVILIJE, INDIANA, ASSIGNOR OF ONE-HALF TO DAVIS M. KITSELMAN, OF SAME PLACE. p

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 279,489, dated June 12', 1883.

Application filed April 25, 1883. (Nn model.) I s To all whom t may concern:

Be it known that I, ALvA L. KITSELMAN, a

citizen of the United States, residing at Ridgeville, in the county of Randolph and State of Indiana, have invented certain new and useful Improvements in Roller-Skates; and I do hereby declare the following to be a full, clear, andeXact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

This invention relates. to certain new and useful improvements in roller-skates, having for its object the production of skates that, while being strong, durable, and light to the feet of the wearer, an equal pressure is adapted to be brought to bear 011 the rubber cush-I ions in whatever position the skates may assume, thus rendering them very easy and comfortable to the person wearing them; and to this end the invention consists in novel features of construction and combination and arrangement of parts, all as will be hereinafter fully described, and set forth in the claims hereto annexed.'

Referring to the accompanying drawings, Figure 1 represents a side elevation of my improved skate; Fig. 2, a longitudinal vertical central section through the rear or front portion of the skate; Fig. 3, a transverse vertical section through the dotted line x x of Fig. 2, and Fig. 4 is a bottom plan.

In the drawings, A represents the sole or foot plate of the skate, formed of wood or metal, as may be deemed expedient, and provided with the usual. fastenings, a a, vfor securing it to the foot of the wearer. To the under side of the foot or sole plate A, and near the heel and toe, are secured metallic plates B B, each one having downwardly-projecting side anges, b' b', between which are placed rubber cushions I) b. The outer end of each plate B has a downwardly-projecting perforated support, c, which forms one of the bearings for one of the journals, c', 'of the seat C, the opposite journal, c2, having its bearing in the perforated vertical portion d of a right-angled support, D, having its horizontal portion d dovetailed to fit in a corresponding groove in plate B, said horizontal portion having an oblong slot, e, through it, by which the rightangled support maybe adjusted longitudinally and secured in Vany desired position by the' setscrew E. This adjustment of the right-angled support permits of the ready removal of the seat C, in order to put in or renew the rubber 5 5 cushions without removing the skate from the foot of the wearer, or to take out or remove any. of the operating parts when desired. The scat C has a central and upwardlyfprojecting beveled tongue, F, cast or formed integral 6o therewith, and which passes between the rubber cushions b b, and is free to act asa pressure on said rubber cushions sidewise in the rocking of the skate, while the seat C acts as a vertical pressureon the rubber cushions, so that while the seat C on one side of the tongue has a direct vertical pressure on one of the rubber cushions the tongue will at the same time have a direct side pressure on the other or opposite rubber cushion, thereby making 7o a double or equal pressure on both rubber cushions at the same time in the rocking movement of the skate, which, in connection with only side flanges, between which the rubber cushions are placed, and leaving the ends open, the rubber cushions have the necessary room to expand, thus enabling the skate to rock laterallywith more ease and freedom of movement to the foot of the wearer than if said cushions were inclosed in a box, as heretofore. The seat C is provided with the usual downwardly-projecting forked o'r bifurcated arms, which form the bearings for the transverse shaft, u )on which the Hoor-wheels G G' are mountec in the usual manner. 85

My improved skate, while possessing strength and durability, involves simplicity as well as cheapness in construction, and which is adapted to rock sidewise or laterally with a freedom of movement that is easy and light upon the 9o foot of the wearer.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-.

l. 4In a roller-skate, the combination of the 95 metallic plate B, having side anges, b b, the rubber cushions b b, arranged between said flanges, and the rocking seat C, j ournaled below the cushions and having a central vertical tongue, F, projecting upwardly between said roo cushions, substantially as and for the purpose herein shown and described.

2. In a roller-skate, the combination of the metallic plate B, having end supporting-bearing, c, and opposite adjustable bearing, d, and side flanges, b b', the rubber cushions b Z), and the rocking seat C, having a central vertical tongue, F, and journals c c2, substantially as and for the purpose herein shown and described.

3. In a roller-skate, the combination of the metallic plate B, having end supporting-bearing, c, side flanges, b b, and dovetailed groove therein, the rubber cushions b b, arranged between said -side flanges, right-angled, dovetailed, and adjustable bearing-support D, and

presenee of two witnesses..
